i loved MACGYVER. he is a great role model as he actively opposes guns, drugs and smoking and is extremely healthy. he also teaches resourcefulness, determination, the importance of facing your fears and the power of knowledge. but most importantly that, if you think it through, you can solve most anything with witty humor and a Swiss Army penknife.
MacGyver is a cool show where (like it says above) he tries to use his smarts to beat the bad guy. There is some violence, mainly fistfights and occasional gunplay. Kids can learn from this how to survive is a dangerous situation.
